The effect of body position changes on stroke volume variation in 66 mechanically ventilated patients with sepsis

Comparison of Central Venous Pressure (Cvp) Score among Patients on Mechanical Ventilator with Head of Bed (Hob) Elevation 30O; Neutral, Right, and Left Side Positions

“…Based on this explanation, the results of this study corroborate the statement of research that has been carried out by Daihua et al, (2012) and Marik & Cavallazzi, (2013). right side due to an increase in the diastolic end diameter of the right ventricle and the right atrium in the left position, allowing the high return to the right atrium (Sen, Aydin & Discigil, 2007;Aries et al, 2011).…”

“…The results of a study conducted by Yoon et al (2006) that the CVP value at right-angled position shows a lower result than the head up or supine position and it is recommended that the level of the transducer should be placed higher. According to Daihua et al, (2012) there is significant influence between changes in position on stroke volume in septic patients with mechanical ventilation. Furthermore, it was stated that head up 30o increases stroke volume and MAP, at right side HoB 30o position, MAP results are 81 ± 12.3 while HoB 30o is left side 83.8 ± 11.6.…”

Intraoperative circulatory management using the FloTracTM system in laparoscopic liver resection

“…Meanwhile, the average SVV value when pneumoperitoneum was not in effect was 4.3%-18.2% (mean, 9.7%), whereas it was 7.3% greater on average during liver transection. With regard to the relationship between body position and SVV, Daihua et al reported that the 30°head-up and prone positions increases SVV because of the associated decrease in SV, but the 30°left or right recumbent position does not affect SVV and SV (20). In the present study, the average SVV value during liver transection in the six cases in the prone or semiprone position was 5.2%-21.7% (mean, 16.1%), and no significant difference was found compared with cases with other positions.…”

Anesthesia for Thoracic Surgical Procedures

“…One study has shown that GDT is at least not deleterious or does not result in pulmonary fluid overload when used for thoracic surgery requiring lateral thoracotomy and OLV [52]. While changing from the supine to the reverse Trendelenburg or prone positions significantly alters SV and thus SVV, 30° left or right recumbent and supine positions do not appear to affect SV or SVV measurements [53]. Kobayashi concludes that SVV, as displayed on the Vigileo monitor, is considered an accurate predictor of intravascular hypovolemia and is a useful indicator for assessing the appropriateness and timing of applying fluid for improving circulatory stability, but only during the perioperative period after esophagectomy [54].…”
